I know my hydrangeas NEVER attract butterflies. I have not gotten rid of them because they came from a neighbor (before I bought my house) and the neighbor has commented on how she is glad I still have them.

Link below shows some butterflies enjoying hydrangeas. I don't know what the hydrangea species are so maybe you can figure it out.

Hi all, It is true that particular year the Hydrangea paniculatas really brought in the swallowtails as pictured on my blog. That was mainly due to the over population of the swallowtails that particular year though. They were everywhere in the garden. Despite this I would highly recommend 'Limelight' any day of the year for a multitude of interest! Thanks for including my link. It's super wonderful to think of butterflies prior to planting.

I have one that when producing nectar does bring in some things but not a ton. It is a panicle. I think it is quickfire but I forget. It is not really a remarkable shrub but it is tough. My other hydrangeas, oakleaf and one of the usual macrophyllas (I think) bring in nothing.

Is there a reason you want hydrangeas? I know you are down in the Cinci area right? In the Dayton area, with the alkaline soil, hydrangeas are not like they would be in an area with acid soil. I remember my grandmother's shrubs on Long Island. They were at least six feet tall with gorgeous blue blooms. But I can't help trying. So, I have some in pots to get the size and blooms.

Anyhow, I know you know butterfly plants but maybe this is a good thread to talk about shrubs other than butterfly bush. On second thought, I will start a new thread!
